Also described are perfume compositions, colognes and perfumed articles including solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, dryer-added fabric softener articles, hair preparations, deodorant compositions and bleaching compositions containing such products thus produced.

This application is a divisional of application for U.S. Pat. Ser. No. 233,861 filed on Feb. 12, 1981, now U.S. Pat. No. 4,304,689 issued on Dec. 8, 1981.

BACKGROUND OF THE INVENTION

The instant invention provides C₁₁ branched chain aldehydes and alcohols defined according to the generic structure: ##STR1## wherein one of X₁ or X₂ is hydrogen and the other of X₁ or X₂ is methyl; and wherein one of Z₁ or Z₂ is hydrogen and the other of Z₁ or Z₂ is hydroxymethyl having the structure: ##STR2## or carboxaldehyde having the structure: ##STR3## which are used to augment or enhance the aroma of perfume compositions, colognes or perfumed articles.

Inexpensive chemical compounds which can provide intense and long-lasting citrusy, green, melony, woody, peanut oil-like and vetiver-like aroma nuances are desirable in the art of perfumery. Many of the natural materials which provide such fragrances and contribute such desired nuances to perfumery compositions are high in cost, unobtainable at times, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.

There is, accordingly, a continuing effort to find synthetic materials which will replace, enhance or augment the fragrance notes provided by natural essential oils or compositions thereof. Unfortunately, many of the synthetic materials either have the desired nuances only to a relatively small degree, or they contribute undesirable or unwanted odor to the compositions.

C₁₁ aliphatic aldehydes and alcohols are well known in the art of perfumery, e.g., n-undecanal and n-undecanol. Oxo reaction products on hydrocarbon compounds are also well known in the perfumery industry. Thus, U.S. Pat. No. 4,146,505 discloses the formation of hydroxymethyl-formyl-tricyclo[5,2,1,0²,6 ]decane having the structure: ##STR4## wherein R₁ and R₂ are the hydroxymethyl group, CH₂ OH or the formyl group CHO and R₁ represents CH₂ OH when R₂ is CHO and vice versa. This polycyclic carboxaldehyde alcohol is indicated to be useful as a musk aroma imparting or augmenting material. The material is indicated to be produced by reaction of carbon monoxide and hydrogen with dicyclopentadiene. Other oxo reaction products on unsaturated hydrocarbons are known in the perfumery industry, for example, "Vandor-B", which is the oxo reaction product of carbon monoxide and hydrogen on diiosbutylene. This material has been produced by International Flavors & Fragrances Inc., the assignee of the instant patent application, for several years.

Nothing in the prior art discloses the use of the C₁₁ aldehydes and alcohols produced by means of carrying out an "oxo" reaction (with carbon monoxide and hydrogen) on one or more diisoamylenes defined according to the generic structure: ##STR5## wherein R₁, R₂, R₃, R₄ and R₅ represent hydrogen or methyl with the proviso that (i) at least one of R₁ and R₂ represents methyl, (ii) at least one of R₃ and R₄ represents methyl, (iii) the sum of the carbon atoms in R₁, R₂, R₃, R₄ and R₅ is 3 and (iv) R₁ and R₂ represent hydrogen when R₅ is methyl; to produce one or more of the compounds defined according to the structure: ##STR6## wherein one of X₁ or X₂ is hydrogen and the other of X₁ or X₂ is methyl; and wherein one of Z₁ or Z₂ is hydrogen and the other of Z₁ or Z₂ is hydroxymethyl having the structure: ##STR7## or carboxaldehyde having the structure: ##STR8##

U.K. Pat. No. 796,130 published on June 4, 1958 discloses the synthesis of polyalkylindanes by means of, interalia, reacting alpha-methylstyrene with trimethylethene (2-methyl-butene-2) in the presence of an acid catalyst such as, sulfuric acid or boron trifluoride etherate. It is further indicated that such compounds are useful intermediates in the production of perfumery compounds. Apparently, however, the more volatile diisoamylenes produced as side-products in the reaction of 2-methyl-butene-2 with alpha-methylstyrene have heretofore been discarded.

Catalytic oxo reactions on 10-carbon atom containing olefins are known to have been carried out according to "Organic Syntheses Via Methyl Carbonyls" Volume 2 by Wender and Pino (Wiley-1977) at Table 5, page 63, wherein it is indicated that the olefin having the structure: ##STR9## is reacted with carbon monoxide and hydrogen to produce a mixture of the three aldehydes having the structures: ##STR10##

Chem. Abstracts, Volume 93, 1980, at 204066f discloses a summary of Japanese Kokia Tokkyo Koho 80-85,534 which discloses the reaction of diisobutylene with carbon monoxide in the presence of cobalt octacarbonyl, dioctylphosphine and dodecylbenzene at 120 kg/cm² and 150° C. for 5 hours yielding isononyl aldehyde and isononyl alcohol.

Nothing in the prior art, however, discloses the use of the oxo reaction product on diisoamylenes in augmenting or enhancing the aroma of perfume compositions, perfumed articles or colognes.

THE INVENTION

It has now been determined that C₁₁ branched chain aldehydes and alcohols defined according to the structure: ##STR18## wherein one of X₁ or X₂ is hydrogen and the other of X₁ or X₂ is methyl and wherein one of Z₁ or Z₂ is hydroxymethyl having the structure: ##STR19## or carboxaldehyde having the structure: ##STR20## and the other of Z₁ or Z₂ is hydrogen produced according to the reactions: ##STR21## followed by, for example, the reaction: ##STR22## are capable of imparting or augmenting or enhancing a variety of fragrances in or to consumable materials.

Briefly, our invention contemplates augmenting or enhancing fragrances of such consumable materials as perfumes, perfumed articles, (e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents, cosmetic powders, fabric softener compositions, dryer-added fabric softener articles and perfumed hypochlorite bleaches) and colognes by adding thereto a small, but effective, amount of at least one of the compounds defined according to the generic structure: ##STR23## wherein one of X₁ or X₂ is hydrogen and the other of X₁ or X₂ is methyl and one of Z₁ or Z₂ is hydrogen and the other of Z₁ or Z₂ is hydroxymethyl having the structure: ##STR24## or carboxaldehyde having the structure: ##STR25##

More specifically, the structures of the compounds useful in practicing our invention are as follows: ##STR26##

The C₁₁ branched chain aldehydes and alcohols of our invention augment or enhance green, citrusy, melony, woody, peanut oil-like and vetiver-like aroma characteristics. The perfumes, perfumed articles and colognes thereby causing one or more of said C₁₁ branched chain aldehyde and alcohol compounds to be useful particularly in citrus and vetiver-type fragrances.

The C₁₁ branched chain alcohol and aldehyde derivatives of our invention defined according to the structure: ##STR27## wherein one of X₁ or X₂ is hydrogen and the other of X₁ or X₂ is methyl and one of Z₁ or Z₂ is hydrogen and the other of Z₁ or Z₂ is hydroxymethyl having the structure: ##STR28## or carboxaldehyde having the structure: ##STR29## may be prepared by first (i) reacting 2-methyl-2-butene in the presence of an acidic catalyst which may be a Lewis acid such as, zinc chloride, aluminum chloride, aluminum bromide, diethyl aluminum chloride, diethyl aluminum bromide, ethyl aluminum dichloride, and diethyl aluminum bromide, boron trifluoride, boron trifluoride etherate, or any of the other catalysts enumerated in the following references:

and then (ii) reacting the resulting mixture or components thereof with a mixture of carbon monoxide and hydrogen using a particular range of temperatures and partial pressures of hydrogen and carbon monoxide over one of several alternative "oxo" type reaction catalysts over a period of residence times.

As to the reaction for forming the diisoamylene (i): ##STR30## depending upon the conditions of reaction, including temperature, pressure, mole ratio of 2-methyl-2-butene:catalyst, concentration of 2-methyl-2-butene and solvent, concentration of catalyst and solvent and time of reaction, the ratio and natures of isomers of diisoamylene produced will vary in an as yet undetermined fashion. In any event, this invention contemplates the use of all isomers of diisoamylene as reactants defined according to the structures: ##STR31## taken alone or in admixture in all proportions, when used for the purpose of reaction with carbon monoxide and hydrogen.

As to the "oxo" reaction (ii) of the resulting diisoamylene derivatives with carbon monoxide and hydrogen carried out, for example, according to the reaction sequence: ##STR32## the reaction is carried out at temperatures of between 150° C. and 300° C. at pressures of between 50 and 250 atmospheres; with the ratio of partial pressure of carbon monoxide:hydrogen being from 0.1:1 up to 1:0.1. Any oxo type reaction catalyst but, most preferably, the catalyst to yield the best perfume mixtures are as follows:

Dicobalt octacarbonyl

Cobalt octanoate

Palladium chloride

Rhodium trichloride

Iron pentacarbonyl

Nickel tetracarbonyl

Polymer-bonded rhodium catalyst (e.g., rhodium bonded on a polystyrene substrate)

Tris-triphenyl phosphine rhodium-1-chloride

Depending upon the conditions of reaction including, temperature, partial pressures of diisoamylene, carbon monoxide and hydrogen, mole ratio of diisoamylene:catalyst, concentration of diisoamylene in solvent, concentration of catalyst in solvent and time of reaction, the ratio and nature of the isomers of aldehydes, the isomers of the alcohols and the ratio of the aldehydes to the alcohols will vary in an as yet undetermined fashion.

In any event, this invention contemplates all isomers of C₁₁ aldehydes and alcohols defined according to the structure: ##STR33## wherein one of X₁ or X₂ is hydrogen and the other of X₁ or X₂ is methyl; and wherein one of Z₁ or Z₂ is hydrogen and the other of Z₁ or Z₂ is hydroxymethyl having the structure: ##STR34## or carboxaldehyde having the structure: ##STR35##

As olfactory agents, the C₁₁ branched chain alcohols and aldehydes taken alone or in admixture, of our invention, can be formulated into, or used as components of a "perfume composition" or can be used as components of a "perfumed article", or the perfume composition may be added to perfumed articles.

The term "perfume composition" is used herein to mean a mixture of organic compounds including, for example, alcohols, aldehydes, ketones, nitriles, ethers, lactones, natural essential oils, synthetic essential oils and hydrocarbons other than the C₁₁ branched chain alcohol and aldehyde derivatives of this invention which are admixed so that the combined odors of the individual components produce a pleasant or desired fragrance. Such perfume compositions usually contain (a) the main note or the "bouquet" or foundation stone of the composition; (b) modifiers which round off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation, and substances which retard evaporation; and (d) top notes which are usually low boiling, fresh-smelling materials.

In perfume compositions, the individual component will contribute its particular olfactory characteristics, but the overall effect of the perfume composition will be the sum of the effects of each of the ingredients and in certian instances, a synergistic effect as a result of the addition of certain ingredients. Thus, the individual compounds of this invention, or mixtures thereof, can be used to alter the aroma characteristics of a perfume composition, for example, by highlighting or moderating the olfactory reaction contributed by another ingredient in the composition.

The amount of the C₁₁ branched chain alcohol and aldehyde derivatives of this invention which will be effective in perfume compositions depends on many factors, including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.05% of the C₁₁ branched chain alcohol and aldehyde derivatives of this invention, or even less, can be used to impart an interesting, herbaceous, piney and woody aroma to soaps, liquid or solid anionic, cationic, nonionic or zwitterionic detergents, cosmetics, cosmetic powders, liquid and solid fabric softeners, dryer-added fabric softener articles, (e.g., BOUNCE® a registered trademark of the Procter & Gamble Company of Cincinnati, Ohio), optical brightener compositions and other products. The amount employed can range up to 70% or even higher, and will depend on considerations of cost, nature of the end product, and the effect desired on the finished product and particular fragrance sought. Thus, for example, when fragrancing liquid bleach compositions containing alkalihypochlorite such as, for example, sodium hypochlorite, for example CLOROX®, (registered trademark of Clorox, Inc.). The amount employed can be as high as 100% of the fragrance involved in the liquid bleach. Indeed, a distinctive aspect of our invention is the use of one or more of the C₁₁ branched chain alcohol and aldehyde derivatives of this invention in a stable liquid bleach composition.

The C₁₁ branched chain alcohol and aldehyde derivatives of this invention, taken alone or in admixture, can be used alone, or in a perfume composition as an olfactory component in detergents, soaps, space odorants and deodorants; perfumes; colognes, toilet waters; bath salts; hair preparations, such as lacquers, brilliantines, pomades and shampoos; cosmetic preparations, such as creams, deodorants, hand lotions, sunscreens; powders, such as talcs, dusting powders, face powders and the like; liquid bleaches, such as sodium hypochlorite-containing bleaches; floor waxes; automobile aromas and automobile polish compositions. When used as an olfactory component of a perfumed article, as little as 0.01% of one or more of the C₁₁ branched chain alcohol and aldehyde derivatives of this invention will suffice to impart an interesting, herbaceous, piney and woody aroma. Generally, no more than 0.5% is required to impart such aromas, however, in view of the rather low cost of the C₁₁ branched chain alcohol and aldehyde derivatives of this invention, up to 100% of the perfume composition can be one or more of the C₁₁ branched chain alcohol and aldehyde derivatives of this invention.

In addition, the perfume composition can contain a vehicle or carrier for the C₁₁ branched chain alcohol and aldehyde derivatives of this invention, alone, or with other ingredients. The vehicle can be a liquid such as a non-toxic alcohol such as ethanol, a glycol such as proplyene glycol, or the like. The carrier can be an absorbent solid, such as a gum or components for encapsulating the composition such as gelatin which can be used to form a capsule wall surrounding the perfume oil, as by means of coacervation.

It will thus be apparent that the C₁₁ branched chain alcohol and aldehyde derivatives of this invention can be utilized to alter, modify, augment or enhance sensory properties, particularly organoleptic properties such as fragrances of a wide variety of consumable materials.

The following examples serve to illustrate our invention, and this invention is to be considered restricted thereto only as indicated in the appended claims.

All parts and percentages given herein are by weight unless otherwise specified.

The diisoundecanals produced according to Example II impart to this citrus cologne formulation an intense, long-lasting citrusy, green, melony aroma with excellent dry, woody nuances.

EXAMPLE IV

The diisoundecanols produced according to Example II (fractions 6, 7 and 8) have peanut oil-like aromas becoming strongly vetiver on dry-out. These peanut oil and vetiver aroma nuances may be utilized to a great extent in inexpensive functional products. The following pine fragrance demonstrates the use of this material in perfume compositions. In this case it is used at a rate of 47.9%:
